Countermovement jump performance assessment using a wearable 3D inertial measurement unit     

Picerno P  Camomilla V  Capranica L 《Journal of sports sciences》2011,29(2):139-146

The aim of this study was to validate a wearable inertial measurement unit (IMU), containing a 3D accelerometer and gyroscope, for the estimation of countermovement jump height. The absolute vertical acceleration of the IMU positioned on the back of the participant at L5 level, compensated for trunk rotations, was used to obtain jump height by applying the equation of free-fall to the motion of the IMU. The methodology was tested on 28 participants performing five countermovement jumps each. A reference value for this quantity was obtained using stereophotogrammetry (35.4 cm, s = 4.9). Jump height scores obtained using the proposed methodology (35.9 cm, s = 5.5) presented no significant difference with respect to stereophotogrammetry (P = 0.61). A low bias of 0.6 cm confirmed the accuracy of the estimate, which also showed a high (r = 0.87) and significant (P < 0.0001) correlation with reference values. Furthermore, without compensating accelerations for trunk rotation, jump height was largely underestimated (P < 0.0001) (bias: -12.7 cm) and poorly associated (r = 0.31) with stereophotogrammetry. The results of this study show that the estimation of jump height using inertial sensors leads to accurate results when the measured accelerations are corrected for trunk rotations.  相似文献   

Estimation of the measurement uncertainty and practical suggestion for the description of the metrological traceability in clinical laboratories

Clinicians request a large part of measurements of biological quantities that clinical laboratories perform for diagnostic, prognostic or diseases monitoring purposes. Thus, laboratories need to provide patient’s results as reliable as possible. Metrological concepts like measurement uncertainty and metrological traceability allow to know the accuracy of these results and guarantee their comparability over time and space. Such is the importance of these two parameters that the estimation of measurement uncertainty and the knowledge of metrological traceability is required for clinical laboratories accredited by ISO 15189:2012. Despite there are many publications or guidelines to estimate the measurement uncertainty in clinical laboratories, it is not entirely clear what information and which formulae they should use to calculate it. On the other hand, unfortunately, there are a small number of clinical laboratories that know and describe the metrological traceability of their results, even though they are aware of the lack of comparability that currently exists for patient’s results. Thus, to try to facilitate the task of clinical laboratories, this review aims to provide a proposal to estimate the measurement uncertainty. Also, different suggestions are shown to describe the metrological traceability. Measurement uncertainty estimation is partially based on the ISO/TS 20914:2019 guideline, and the metrological traceability described using the ISO 17511:2020. Different biological quantities routinely measured in clinical laboratories are used to exemplify the proposal and suggestions.  相似文献

Designing Reading Comprehension Assessments for Reading Interventions: How a Theoretically Motivated Assessment Can Serve as an Outcome Measure     

Tenaha O’Reilly  Jonathan Weeks  John Sabatini  Laura Halderman  Jonathan Steinberg 《Educational Psychology Review》2014,26(3):403-424

When designing a reading intervention, researchers and educators face a number of challenges related to the focus, intensity, and duration of the intervention. In this paper, we argue there is another fundamental challenge—the nature of the reading outcome measures used to evaluate the intervention. Many interventions fail to demonstrate significant improvements on standardized measures of reading comprehension. Although there are a number of reasons to explain this phenomenon, an important one to consider is misalignment between the nature of the outcome assessment and the targets of the intervention. In this study, we present data on three theoretically driven summative reading assessments that were developed in consultation with a research and evaluation team conducting an intervention study. The reading intervention, Reading Apprenticeship, involved instructing teachers to use disciplinary strategies in three domains: literature, history, and science. Factor analyses and other psychometric analyses on data from over 12,000 high school students revealed the assessments had adequate reliability, moderate correlations with state reading test scores and measures of background knowledge, a large general reading factor, and some preliminary evidence for separate, smaller factors specific to each form. In this paper, we describe the empirical work that motivated the assessments, the aims of the intervention, and the process used to develop the new assessments. Implications for intervention and assessment are discussed.  相似文献   

Morningness–Eveningness and College Advising: A Road to Student Success?     

Beverly Brown Schulke  Laura K. Zimmermann 《Mind, Brain, and Education》2014,8(4):227-230

In addressing the challenges faced by E‐type (evening‐type) students, researchers have pointed to the need for school schedules that reflect chronotypic concerns and the recognition of the importance of sleep for academic achievement and well‐being. One approach to dealing with this issue for adolescent students has been to move the start of the school day later. In college, however, schedules become more varied and the social context in which these challenges occur differs requiring more individualized approaches to scheduling. In spite of this, morningness–eveningness is rarely considered by college administrators, advisors, or individuals involved in student services. It is important that faculty and staff who work with students be aware of chronotypical influences on classroom performance and other aspects of student life so that they can help them succeed in college and beyond.  相似文献   

Impact Factor: Early Career Research & Digital Scholarship     

Laura A. Pasquini  Jenny S. Wakefield  Tiffany Roman 《TechTrends》2014,58(6):12-13

It is becoming increasingly vital to publish and share research as well as get citations for the purpose of researcher visibility. The publishing options available for research distribution seem endless. It really is an academic jungle out there! This article reviews why early career researchers and graduate scholars should consider their research impact in the digital age.  相似文献   

An Experimental Test of Medical Disclosure and Consent Documentation: Assessing Patient Comprehension,Self-Efficacy,and Uncertainty     

Erin E. Donovan  Brittani Crook  Laura E. Brown  Angie E. Pastorek  Camille A. Hall  Michael S. Mackert 《Communication monographs》2014,81(2):239-260

Effectively conveying risks and hazards in medical disclosure and informed consent documentation is a crucial type of communication. However, existing protocols typically do not meet the needs of patients or practitioners. In the present study, we advance a reconceptualization of obtaining written informed consent by analyzing it as a process of uncertainty management rather than a matter of document readability and recall. Results of this randomized trial indicated that patients who reviewed a simplified consent document reported greater comprehension of medico-legal terminology and lower uncertainty about the document, although they did not evince greater self-efficacy. Health literacy was a significant moderator of the relationship between consent form version and comprehension.  相似文献
